 ### 完全基于文件的查询
 
+```javascript
+// 导入包
+const Searcher = require('.')
+// 指定ip2region数据文件路径
+const dbPath = 'ip2region.xdb file path'
+
+try {
+  // 创建searcher对象
+  const searcher = Searcher.newWithFileOnly(dbPath)
+  // 查询
+  const data = await searcher.search('218.4.167.70')
+  // data: '中国|0|江苏省|苏州市|电信'
+} catch(e) {
+  console.log(e)
+}
+
+```
+
 ### 缓存 `VectorIndex` 索引
 
+```javascript
+// 导入包
+const Searcher = require('.')
+// 指定ip2region数据文件路径
+const dbPath = 'ip2region.xdb file path'
+
+try {
+  // 同步读取vectorIndex
+  const vectorIndex = Searcher.loadVectorIndexFromFile(dbPath)
+  // 创建searcher对象
+  const searcher = Searcher.newWithVectorIndex(dbPath, vectorIndex)
+  // 查询 await 或 promise均可
+  const data = await searcher.search('218.4.167.70')
+  // data: '中国|0|江苏省|苏州市|电信'
+} catch(e) {
+  console.log(e)
+}
+```
+
 ### 缓存整个 `xdb` 数据
 
+```javascript
+// 导入包
+const Searcher = require('.')
+// 指定ip2region数据文件路径
+const dbPath = 'ip2region.xdb file path'
+
+try {
+  // 同步读取buffer
+  const buffer = Searcher.loadContentFromFile(dbPath)
+  // 创建searcher对象
+  const searcher = Searcher.newWithVectorIndex(buffer)
+  // 查询 await 或 promise均可
+  const data = await searcher.search('218.4.167.70')
+  // data: '中国|0|江苏省|苏州市|电信'
+} catch(e) {
+  console.log(e)
+}
+```
